- ID2020 seeks to provide every child born after 2020 with a self sovereign digital identity, which helps reduce risks of trafficking and drive digital inclusion.
- Shocard is an early stage company developing an “identity platform” built on blockchain. A user’s identity is encrypted, hashed and then written to the blockchain, where it can be called up when needed. Users would, in effect, give banks temporary access to the private side of this blockchain record in order to verify identity. Once that is done, the bank creates its own record that can be consulted in the future to determine that a certain Joe Smith is really Joe Smith.
- A research team at Athens University of Economics and Business is working on “information-centric” networking and is exploring the use of blockchain technology for “content names”.
- The U.S. Department of Homeland Security is funding research on the "Applicability of Blockchain Technology to Privacy Respecting Identity Management"
- An MIT paper about "Decentralizing Privacy: Using Blockchain to Protect Personal Data".
- An Ethereum blog post about "Privacy on the Blockchain", including some thoughts about identity systems.
- Jolocom is developing applications for everyone to own their personal digital identity, using linked data and blockchain technologies.
- Danube Tech is collaborating with several other efforts to build blockchain-based identifier registration infrastructure.
- Scuttlebot is a "blockchain identity" protocol avoiding a singleton-based approach. It embraces subjectivity over consensus, e.g. each identity can publish messages that map their favorite pet name mappings for themselves and others. Patchwork is a user-facing decentralized messaging and sharing app based on Scuttlebot.
- Startup Cambridge Blockchain is working on an Identity Blockchain for validating secure digital identity documents, processing electronic signatures, and recording transactions.
- Proof-of-Individuality addresses the challenge to prove that a person only has one account within a system, without sacrificing the advantages of anonymity/pseudonymity. See here for a draft implementation using "virtual pseudonym parties".
- Regis is a platform that makes it easy to build, deploy, and manage decentralized registries on the Ethereum blockchain.
- SingleID An app that allows you to be in control of their online identity. It provides safe logins with no registration and no password.
- IDKeys is a distributed global identity system that registers cryptographic public keys on the Stellar blockchain.
- CheapID is a digital identity standard designed for use in conflicted environment like those many refugees or disaster victims may find themselves in.
- DIDs (Decentralized Identifiers) are a new type of identifier intended for digital identity that is "self-sovereign", i.e, fully under the control of the identity owner. DIDs resolve to DDOs (DID descriptor objects) and can be registered in different blockchains (using different "methods").
- A research project on registering WebIDs on the Ethereum blockchain, to be used for Linked Data and Solid.
- An article by the GSMA about the relationship between blockchain and identity.
- Bitnation: Bitnation is a governance 2.0 platform that is powered by blockchain technology. Its goal is to provide the same services that governments provide, but in a decentralized and voluntary manner, unbound by geography. Bitnation has worked out an identification solution such as blockchain passport and a marriage certificate.
- 2WAY.IO: 2WAY.IO effectively transforms public nodes into private nodes by adding a permissions layer. Private nodes can connect information silos & secure communication channels. They’re user-in-control (privacy-by-design & security-by-design) and require no trade-off between security & UX. These systems are both trusted third-party- and blockchain-agnostic; they only require an intermediary or blockchain when both parties agree to add one to their interaction.
- Trunomi: Solves KYC and unlocks new revenues and efficiencies with technology to easily create and securely manage the consent to use customers’ personal data. Trunomi securely connects financial institutions to their customers with a “customer-driven” data-sharing platform.

- BlockAuth: BlockAuth enables you to own and operate your own identity registrar that allows users to submit their information for verification.
- Case: Provides biometrically secured multisignature bitcoin transactions. Case is a multisignature, multifactor wallet that requires two of three keys for a transaction to take place. Each key is generated and stored in a different location and is protected by a different authentication factor so that there’s no single point of failure.
- Airbitz A bitboin wallet/ identity solution
- Mooti is the new standard for cryptographic identification and validation. based on our identity chain technology, we are reimagining the security of personally identifiable information and authentication.
- BlockVerify: Provides blockchain-based anti-counterfeit solutions. It uses blockchain technology to improve anti-counterfeit measures in different industries such as pharmaceuticals, luxury items, diamonds and electronics.
- Cryptid: Cryptid eliminates the possibility of counterfeit identification by adding factors of identification and encryption. Cryptid takes the data provided in the form and package it into a compact format readable by our systems and generate your Cryptid identification data. All of the data is encrypted with the provided password after which it is permanently transferred to the blockchain. The customer is then given a unique identification number that points to the information on the block chain and can be stored on almost anything from magnetic stripes to QR codes.
- Guardtime: Guardtime KSI Cybersecurity Platform enables organizations to assure the integrity of their networks, prevent data loss of critical digital assets and to verify enterprise behaviors.
